html css 可滚动表格不会与上面的表格对齐

第一个表格是固定的，当第二个表格向下滚动时，它会留在 View 中。如何使这两个表对齐？

#index_table,
#index_table_header {
  text-align: left;
  margin: 20px;
  margin: 0 auto;
  table-layout: fixed;
}

#index_table,
#index_table_header {
  width: 800px;
}

#index_table {
  display: block;
  height: 390px;
  overflow-y: scroll;
}

#index_table_header td {
  padding: 10px 8px;
  width: 100px;
  border: 1px solid black;
}

#index_table td {
  padding: 10px 8px;
  width: 100px;
  border: 1px solid black;
}

#index_table td:nth-child(1),
#index_table_header td:nth-child(1) {
  width: 80px;
}

#index_table td:nth-child(3),
#index_table_header td:nth-child(3) {
  width: 70px;
}

#index_table td:nth-child(5),
#index_table_header td:nth-child(5) {
  width: 200px;
}

#index_table td:nth-child(2),
#index_table_header td:nth-child(2) {
  width: 250px;
}

<table id="index_table_header">
  <thead>
    <tr>
      <td>ID</td>
      <td>Item</td>
      <td>Amount</td>
      <td>Added</td>
      <td>Nutritional Value ID</td>
      <td>Actions</td>
    </tr>
  </thead>
</table>
<table id="index_table">
  <tbody>
    <tr>
      <td>395</td>
      <td>chicken liver</td>
      <td>0.37</td>
      <td>2019-10-14</td>
      <td>67</td>
      <td>
        <a href="/delete/395">Delete</a>
        <br>
        <a href="/update/395">Update</a>
      </td>
    </tr>
</table>

一些需要考虑的事情

我需要表格和表格单元格(列)完全对齐
第二个表格实际上有数百行，我希望它可以滚动并且我不希望标题从 View 中消失，这就是为什么我有两个表格并且我不想合并为一个表格的原因。

最佳答案

您可以使用此代码
